Murder on the Orient Express/Fridge

Fridge Brilliance

• In the 1974 Murder on the Orient Express, every time Poirot finishes questioning a suspect, Bianchi (I think) says "It was (her/him)! (He/she) did it!" He's right, of course, every time.
• In the book, when they learn the victim was repeatedly stabbed, Monsieur Bouc immediately labels it a crime of passion and says that the murderer must be a woman. Actually, the crime was ruthlessly planned in advance, but it was a woman who did all the planning and organizing. Well played, Agatha.
